This was a night out of long ago, a standard-definition replay, one of those evenings the Garden used to specialize in back in the day. Maybe the Blazers aren’t the Jordan Bulls, or the Mourning Heat, and maybe the Knicks aren’t quite the princes of the city their forebearers were.

On this night, though? This night, it was hard to tell. Or to care.

Here was Derrick Rose, bleeding the shot clock, drawing every last one of the 19,812 customers to their seats. The Knicks had the chance to deliver a knockout blow, up two, less than 10 seconds to go, but they weren’t getting there easily.

Kristaps Porzingis (31 points, 13-for-23 from the floor) hadn’t touched the ball in over five minutes. Carmelo Anthony (17 points) had touched it plenty, but had gone scoreless in seven fourth-quarter minutes, had missed his last seven shots, and he was working the last nerve of just about everyone in the house.

The game clock tumbled under 9. The shot clock bled to 3 … to 2 … to 1 …

“I’m used to having the ball in my hands there,” Rose would say later. “I’ve been playing like this my whole life.”

It wasn’t just that Rose connected on the step-back 14-foot jumper at the shot-clock buzzer that doubled the Knicks’ lead with 6.8 seconds to go, which secured a 107-103 victory — easily the most satisfying win for this franchise in a couple of years — that sent the Garden into spasms of glee when it was over.

It was how he did it. It was the absurdly confident stroke he put on the ball, and the way he walked away after watching it splash through. Satisfying? For Rose, this was the culmination of something beyond that, five years of on-again and off-again, of starts and stops, of knees that kept sabotaging one of the league’s splendid talents.

“Your whole life you’re used to playing in a rhythm,” Rose said when his 18-point, five-assist, two-steal night was complete. “And then you have an injury and it resets everything. I’ve been playing catchup ever since.

For much of the night, it seemed if the Knicks were going to trip up the Blazers, somehow keep Damian Lillard from breaking their hearts, it would have to be someone other than Rose who would get it done, since he was hamstrung with foul trouble.

Brandon Jennings replaced him and delivered an 11-assist, zero-turnover masterpiece before suffering cramps. Willy Hernangomez and Mindaugas Kuzminskas came off the bench and kept the Knicks within range. Before he fell into a shooting funk, Anthony had hit half of his first 14 shots.

And of course there was Porzingis, in full unicorn mode, electrifying the Garden, electrifying his teammates, pouring in eight points in the first six minutes of the fourth quarter, his 25-foot 3-pointer cutting the Portland lead from four to one, 97-96, with 6:20 left in the game.

But it was Rose who had the final say, which is the only thing he’s really thought about for most of these past five years, waiting for his body to get healthy again, waiting for his game to recalibrate. For much of the season’s first month there were glimpses and glances of what he used to be, which in 2011 was the MVP of the whole league, even in the teeth of LeBron James’ prime.

“He’s thinking too much instead of reacting and playing,” Knicks coach Jeff Hornacek said before the game. “But he’s trying to do the right thing. He’s picking it up on the fly. It may take a little longer, but he’ll get it.”

Finally, with the game there for the taking, Rose seized it.

His 8-foot jumper brought the Knicks to within 101-100 with 3:40 left. Twenty-five seconds later, he delivered a dagger straight out of 2010, his second reverse layup of the night, and the Knicks led by a point. And 41 seconds after that, he found Kuzminskas wide open behind the arc. His 3 made it 105-101.

And that’s when the Garden really felt like someone had rolled the tape back to 1999 or so.

“I have a chance to re-establish myself,” Rose said, and that’s exactly what the Knicks were hoping for, heart of hearts, when they dealt for him in the summer. That, and more than a few nights like this one, when the Garden feels like the only place in the city that anyone could possibly want to be. Just like back in the day.
